JOHN W. PEARSON, OF DAYTON, OHIO, ASSIGNOR TO THE DAVIS SEVVING MACHINE COMPANY, OF DAYTON, OHIO, A CORPORATION OF DELAWARE.

(HEARING.

Application filed December 24, 1921. Serial No. 524,644.

To ll whom it may concern: I Be'it known that 1, JOHN W. PEARSON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain; new and useful Improvements in Gearing, of which the following is a specification, reference being had therein to the accompanying drawing;

My invention relates to gearing and in particular to the driving mechanism for a domestic washing machine.

The object of my invention is to provide a swinging driving means which will be adapted to actuate in any position such mechanism as a swinging wringer swinging therewith slowly and positively and at the same time reciprocate a washing machine tub.

It is an object of my invention to pro *vide a power and wringer unit swinging together above the frame and tub. It 1s a further object to provide this unit wlth a driving member and protecting'casing for the remote drive, at an angle thereto, of

anactuating shaft. It is an additional object to provide in this combination reciprocatingineans to reciprocate the tub driven in connection withthis rotating means.

It is a further object of my invention to provide a system of gearing and chain drive which will permit ofthe accomplishment of these objects.

Referring to the drawings:

' Fig. 1 is an end elevation of the machine with a portion of the swinging housing cutaway to show the method of applying the I drive;

Fig. 2 is an enlarged detail looking to the right from the left hand side of 1 showing a portion of the casing in section and illustrating the details of the lower end of the drive.

Fig. 3 is a detail view of the wringer rolls and the drive thereof.

In detail in the drawings, 1 is a frame work of any desired character in which a tub 2 is journaled at 3 on a shaft 4. This shaft is supported by a spider 5 on the end of the tub. There is a duplicate spider and shaft with suitable support at the other end of the tub. A lid 6 is provided for access to the tub.

Attached to this spider 5 is a stub shaft 7 to which is connected a pitman 8 that is pivoted at-9 through a crank 10 carried by horizontal shaft 11 supported on a bracket- 12 in which it is journaled. This shaft 11 carrles a gear 18 which is beveled and in turn driven by a small bevel pinion 14. 14 is supported on the casting 12 and rests thereon, having its shaft 15 projecting therein. 15 also projects intothe casing 16 which constitutes a housing for achain drive to be hereinafter explained as well as the housing for certain gearing. This housing 16 rests upon the gear 14 lightly as it is supported at the top on the shoulder 17. upon the frame 1.- Upon the upper end of 15 is a bevel gear 18 meshing with a bevel gear 19 carried on a cross shaft 20 upon which is a sprocket wheel 21 actuated by a chain 22. On the upper end of the casing 16 isa gear casing 23 in which is journaled a shaft 24 of a gear 25 thatis actuated by a worm 26. This worm 26 is driven by a shaft 27 which is connected to. the motor 28. On this shaft is mounted a sprocket wheel 29 which actuatesthe chain 22. 30 is the wringer with rolls 81 geared to one another by the gears 3,2.32. The upper gear 32 is driven by the shaft 24. i

It will thus be seen that as the casing 16 swings about on the frame 1 the entire actuating'mechanism will swing as a unit and the gear 19 will ride around upon 18 while the wringer may be actuated in any position as desired.

While I have shown and described certain features as constituting my invention, it will be understood that parts have been shown for purposes of illustration only, and that I do not desire to be limited to such details, as obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination, a source of power, a driven shaft, a worm and gearing connected therewith, a second shaft connected to said gearing and a wringer driven thereby, a sprocket on the first mentioned shaft, a chain thereon, a single tubular housing for said chain which travels therein and rotates with the housing bodily, a cross shaft with a sprocket thereon journaled at the bottom of said casing, a gear thereon, a second gear meshing therewith on a vertical shaft, a vertical shaft, a crank, intermediate gearing adapted to drive the crank, a pitman, and means to be reciprocated by said pitman.

2. In combination, a frame, a source of power, a driven shaft, a worm and gearing connected therewith, a second shaft connected to said gearing, a wringer driven thereby, a sprocket on the first mentioned shaft, a chain thereon, a housing for said chain, a cross shaft with a sprocket thereon journaled at the bottom of said (casing, a gear thereon, a vertical shaft, a second gear meshing therewith on a vertical shaft, a crank, intermediate gearing adapted to drive the crank, 21 pitinan, means to be reciprocated by said pitman, said casing carrying the source of power and the adjacent gearing, sprocket wheels and chain being adapted to rotate upon a frame, whereby the wringer can be operated in any position and means to :be reciproca-ted can be reciprooated irrespective of the position of the wringer.

3. In combination, a frame, a casing adapted to move thereon, said casing contaming gearing, gearing, a source of power mounted on said casing to actuate said gearing, a wringer mounted on said casing to be actuated by said gearing, whereby the whole may turn as a unit and operate in various positions, a depending tubular member, a chain passing therethrough actuated by the source of power, stationary gearing at the bottom of said depending casing actuated by said chain, means connected with said gearing to be reciprocated, the connection between the chain and the stationary gearing being adapted to transmit power in all positions of the casing and the mechanism mounted thereon.

4:. In combination, a frame, a casting rotating therein, extending above and projecting below said frame, said casting being adapted to house a chain moving therein and said casting consisting of a single tubular member, a supplementary gear casing, gearing in the ,top of the casting, a source of power mounted on the top of said casting adapted to drive said chain and adapted to drive gearing mounted adjacent the top of said casing in the supplementary gear casing, gearing located within said casting at the bottom thereof, said gearing adapted to actuate a vertical shaft journaled in said casting at the bottom thereof, a vertical shaft, a second supporting casting below the first mentioned casting but mounted permanently on said frame, a gear interposed between said castings and mounted on said vertical shaft journaled in both of said castings, a second shaft journaled in the second casting, agear mounted on said second shaft meshing with said last mentioned gear and means on said last mentioned shaft for imparting reciprocatory movement to a link member, and a link member, whereby in a single casting supported by the frame and turning upon the second casting, the entire unit of the chain, gear driving the chain, power unit, gearing and wringer will turn freely upon the frame upon the second asting while maintaining driving connection with the link member.

In testimony whereof I aifix my signature.

JOHN WV. PEARSON.
